protectedvirtual

Make a clone of this object, possibly modifying the cloned object to make it sane.

Returns: a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

inlinevirtual

Return true, if this amplitude is capable of calculating one-loop (QCD) corrections.

Reimplemented from Herwig::MatchboxAmplitude.

Definition at line 61 of file MatchboxAmplitudehbbbarg.h.

◆ Init()

static void Herwig::MatchboxAmplitudehbbbarg::Init ( )

static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

◆ isBDK()
